Free Online Extract Audio from Video
Pull Just the Audio Track Out of Any Video
Need to use Extract Audio from Video right now?
Plenty of video content is really audio content that happens to have a picture attached — a recorded lecture, a podcast filmed on video, a music performance, an interview. Getting just the sound out without the video usually meant opening a video editor just to export audio. This tool does exactly that in one step: upload a video, get back an MP3 of just its audio track.

About Extract Audio from Video
Plenty of video content is really audio content that happens to have a picture attached — a recorded lecture, a podcast filmed on video, a music performance, an interview. Getting just the sound out without the video usually meant opening a video editor just to export audio. This tool does exactly that in one step: upload a video, get back an MP3 of just its audio track.
A real FFmpeg build compiled to WebAssembly runs the extraction entirely inside your browser, decoding the video's audio stream and re-encoding it as MP3 at a high quality setting (VBR quality level 2, a strong balance of size and fidelity) — this works regardless of what audio codec the original video actually used internally, since FFmpeg decodes it first before re-encoding.
The video stream itself is discarded entirely during processing rather than merely ignored in the output, so no video data is retained or wasted — the result is purely and only the extracted, re-encoded audio.
This handles any video container your browser's FFmpeg build can read (MP4, WebM, MOV, AVI, MKV, and more), making it a general-purpose "get the sound out" tool rather than being tied to one specific video format.
How it works
- Upload your video. The file loads into the browser-based FFmpeg engine.
- Audio is extracted and encoded. The audio track is decoded and re-encoded as MP3.
- Download the MP3. Just the sound, with the video discarded entirely.
